The invention discloses a vehicle trajectory clustering generation method, which comprises the following steps of: firstly, information acquisition: acquiring vehicle id information, vehicle category information, vehicle position, vehicle outline and other information of a vehicle tracking target in a frame where a video is located based on a target tracking algorithm; according to the invention, a better track clustering effect is achieved in vehicle track clustering; according to the method, vehicle traveling tracks in different vehicle flow directions can be clearly clustered, vehicle flow data of different types of vehicles in different tracks can be obtained, a result is visually displayed in an interface in an image form, and the size and color of the vehicle flow are represented based on the thickness of a drawn line so as to distinguish different tracks; the method is used as a trajectory clustering technology in automatic generation of trajectories of vehicles shot by an unmanned aerial vehicle or ot
